The present disclosure extends to methods, systems, and computer program products for routing following vehicles toward a lead vehicle in a vehicle caravan. GPS locations can be shared between caravanning vehicles moving towards a destination. Routes (e.g., turn-by-turn navigation) for individual vehicles participating in a caravan can be dynamically updated. Within a group of GPS devices, one GPS device (e.g., a GPS device at a designated lead vehicle) can be selected as a master GPS device. As the designated lead vehicle travels towards the destination, the master GPS device can continually share its GPS coordinates (i.e., share its location) with the other GPS devices. The other GPS devices use the shared GPS coordinates to continually adjust routes to progress towards the master GPS device (and thus progress towards the lead vehicle). That is, the other GPS devices are continually updating navigation routes to follow the master GPS device.
